ROLLER-BEARING.

Specification of Letters Patent.

Application filed May 10, 1909. Serial in. 495,032.

To all whom it may concern:

Be it known that I, ELIEL L. SHARPNEUK, of Winthrop, in the county of Suffolk and State of ltlassachusetts, have invented a new and useful Improvement in Roller- Bearings, of which the following is a specification, reference being had to theaccompanying drawings, forming part thereof.

This invention relates to improvements in roller bearings and refers particularly to the means whereby frictional resistance be tween movable parts of the bearing is reduced. t

The object of the invention is to' so construct a roller bearing comprising a cage and antifriction rolls rotatably mounted therein, that frictional resistance is reduced between the ends of said cage and the stationary parts of the box in which the hearing is contained.

The invention consists in such novel feutures of construction and combination of parts asshall hereinafter bemore fully described and pointed out in the claun.

Figure 1, represents a sectional view of the improved roller bearing, taken on line -11 Fig. 1'2, showing the bearing as applied to a journal box for car axles. Fig. 2, represents a sectional view of the same taken on line 2 2 Fig. .l. a

Similar numbers of reference designate correspomling parts throughout.

' For the purpose of illustrating one use of this improved roller bearing the sameis shown herein as contained within a journal box having the cvhndrieal inner wall 5 and the end wall'tl having the axial opening 7. Provision is made for closing the open -cnd of said box by mean'sot' the cover S having thepocket. 9 in which is seated an antifriction block formed by the segmental wooden members 1() -1O having between them the diametrically extending la vcrs llll, preferably of raw hide, which form a thrust bearing for the shaft A which extends through the opening 7.

\Vithin the journal box is a cage comprising a pair of annular metallic members 12-42 each havingsockets attheir inner sides to receive the. ends of the roll shafts 1313 and, at their outer sides having sockets to receive and hold in position the antifriction plugs 1414 formed of wood and raw hide or other material adapted to absorb lubricant. I On each of the roll shaft. 13 is journaled a pair of antifriction rolls each of .which comprises the metallic shell 15, adapted to contact withthe wall 5 and with the eriphery of theshaft A, and the wooden ushing 16 driven into said shell 15 and'having a. bore shaft 13.. Antifriction washers 17-17 and 18-18 are also provided on the shafts to separate, respectively, the pairs of antifrlct-ion rolls and the ends of said rolls from the annular members 12-42.

By the use of this device the antifriction rolls are freeitorotate independently between the surface of the cylindrical way 5 and the periphery of the shaft A while each pail; of said rolls ma rotate independently, Ont-heir shaft. he entire cage 15 also free to rotate and series of antifriction plugs 14-14= may at times contact with the ends of the journal box and are adapted to reduce the frictional contact therewith while said plugsarc so mounted that they are positiv'ely moved with the cage. The wooden bushings 16, the plugs 1-l-14 and the thrust block carried by the cover'Sare all preferably saturated with lubricant of some well known nature.

Having thus described my invention I claim as new and desire to secure by Letters Patent.

' A roller bearing comprising a casing having a cylimlrical way and ends. and acage contained within said wayand having annular end members furnished at their outer surfaces with antit'riction plugs. ti.\'ed to said end members. shafts mounted in said end members. and a pair of antifriction rolls rotatably mounted on each of said shafts,

journaled onthe the respective Patented Dee.13, 1910.

said rolls. of each'pair being sepa'iated by washers as-and for the purpose described. ELIEL L. SHARPNECK. \Vitnesses: 4 I
